Arnold Jacobs Adjustable Cup Tuba Mouthpiece Gold

Arnold Jacobs had three Adjustable Cup tuba mouthpieces made for him. Jacobs used these mouthpieces to be able to adjust the tone and character of the sound without changing mouthpieces during a performance.  After he passed away these three were given to some of his closest students. Unfortunately one was stolen. The CHI BRASS Arnold Jacobs Adjustable cup mouthpiece is an exact hand made precision copy made in the USA of the one currently belonging to Brian Frederiksen,  Author of Arnold Jacobs Song and Wind.  This mouthpiece duplication is done in conjunction with Windsong Press. Not only to make this mouthpiece available to others but to continue passing on Jacobs’ legacy of teaching, artistry, innovation and brass playing philosophy.  Each Adjustable Cup Mouthpiece is made by Hand, one at a time, by a master craftsman in the U.S.

Please note that the much higher expense for gold on this mouthpiece is due to much more surface area overall and the two pieces are plated separately.

*Since these are made in small batches and not many are in gold when sold out it may take a long while for more to be available to order. To have one of the next available batch reserved for you email [email protected] to make arrangements.
